摘　　要：为解决竖炉脊顶高温工矿条件下变形开裂的难题，在对脊顶变形开裂原因进行分析的基础上。提出了改造措施。将原设计等腰三角形结构改为平直形脊顶，利用球团自然堆角覆盖，对脊顸进行保温保护的特性，解决了竖炉脊顶高温状态下变形开裂的难题，使用寿命比原设计等腰三角形脊顶提高了10倍。In order to settle the difficult problem of deforming and cracking of a shaft furnace＇s ridge under high - temperature conditions, reform measures were put forward on the basis of an analysis of causes of deforming and cracking of the ridge. The change of originally designed iSosceles-triangle structure to flat-straight one, and the use of the characteristics of pellets＂ natural angle of rest to protect the ridge with heat preservation, settled the problem, making its service life 10 times longer than the original one.
